Cornered and captured in Gloucestershire, the good captain is taken to some woods and summarily lynched by Gowan – only to be rescued by a daring young boy named Francis (Keith Jayne). Assisted by a local poacher, Caleb, Francis helps to nurse the captain back to health. Now Captain Jack swears revenge upon Gowan and his gang and prepares for vengeance – even as Gowan discovers Jack’s body is missing and begins to hunt him down in turn… Made by Southern Television for the ITV Network.
